Kevin Federline has come seventh in a list of the '50 Most Influential Men under 45'. The star, the ex-husband of Britney Spears, came in joint seventh position along with the late Anna Nicole Smith's lover Larry Birkhead in 'The Good Fathers' category in the list compiled by Details magazine.
The publication wrote: "Meet America's new parental role models. We all expected Kevin Federline and Larry Birkhead to crash and burn as fathers. Instead, by being more visible presences in their children's lives than many Hollywood A-listers, they emerged as unlikely candidates for Dad of Year. The New Dad, as represented by Kevin and Birkhead, is involved. He trucks the kids to the supermarket, decorates their bedrooms, and even lets them dictate the direction of his career."
The list was topped by 'High School Musical' star Zac Efron who, along with 'Indiana Jones and the Crystal Skull' actor Shia LaBeouf and the 'Disney Kids' - including Hannah Montana and Hilary Duff - took joint number one spot. Details attempted to justify the positioning, commenting: "If you think you can escape Disney's mind-controlling power, think again. Like it or not, we're all caught in the mouse's trap!" Mark Zuckerberg, who founded social networking site Facebook, came third on the list, while Eric Harris and Dylan Klebold - who went on a shooting rampage and killed pupils in their respective high schools - controversially rounded out the top five. |
